Checking Results

Checking Results#

To check whether your MPI implementation is working correctly, you can use the CPP flag -DCHECK.

Activate the CPP flag -DCHECK through the CPPFLAGS variable and recompile the Intel(R) MPI Benchmarks executable files. Every message passing result from the Intel(R) MPI Benchmarks are checked against the expected outcome. Output tables contain an additional column called Defects that displays the difference as floating-point numbers.

Note

The -DCHECK results are not valid as real benchmark data. Deactivate -DCHECK and recompile to get the proper results.
